Class SimpleKryoKeyValueStore<V extends Serializable>

java.lang.Object

org.boon.slumberdb.base.BaseSimpleSerializationKeyValueStore<String,V>

org.boon.slumberdb.impl.SimpleKryoKeyValueStore<V>

Type Parameters:

V - type of value we are storing.

All Implemented Interfaces:

Closeable, AutoCloseable, SerializedJavaKeyValueStore<String,V>, KeyValueStore<String,V>

public class SimpleKryoKeyValueStore<V extends Serializable>
extends BaseSimpleSerializationKeyValueStore<String,V>
implements SerializedJavaKeyValueStore<String,V>

This marries a key value store with Kryo for valueObjectConverter and valueSerializer support. It is a decorator. The real storage is done by the KeyValueStore store. You specify the object type.

This class is not thread safe, but the KeyValueStore likely is. You need a SimpleKryoKeyValueStore per thread. This is needed to optimize buffer reuse of Kryo.

You can combine this Kryo store with any KeyValueStore store.

It expects the key to be a simple string and the value to be an object that will be serialized using Kryo.
